Luke Morgan adds a dash of Kentucky folksiness to the sophisticated atmosphere of old San Francisco and of the wealthy hacienda which belonged to Don Gonzales, whose daughter had married Luke's brother. His story is fairly diverting although coincidence-ridden. Luke just happens to come to town on the same boat which carries Bert Lafferty, the man who will try to rob Gonzales of his land, and Cato Hunt, the one lawyer who will be able to help Luke--a generous amount of intuition leaves Luke correctly pre-disposed toward the two. On arriving in San Francisco, Luke then happens to get into a brawl with Lafferty's partner and to rescue a very helpful Chinese, and he continues to run into the same people on all his visits to the city. A capture and escape from Indians firms up the friendship between Gonzales' son (who had hated Americans) and Luke. The two boys, despite their youth, manage to take charge of rescuing the deed from theft and to work out a peaceful compromise between Gonzales and the Tennessee settlers who had been eager to read about the far west.
